As part of our experiments in interaction and play, we decided to create a Tail that we could wear on our journeys around town. We wanted an extra limb that could do all the naughty things you dream of, but don't dare. Having a Tail lets you express your cheeky side. It gives a voice to your emotions even when you're standing still.. And it looks fabulous out and about!

So we have been working on creating the perfect Tail for some years. The video above is of an early prototype. Our final prototype is much more advanced - being fully controllable, it can bend and flex and knock things off tables, tremble and twist and curl, stand up and of course wag and get frisky.. It can also dance in time to music - but more about that later..

They're not looking for all that much money (£10,000 by September 12) and the rewards seem reasonable, assuming you are also looking to have a tail that can dance to music. Keep in mind, however, I suspect local law enforcement might not accept "cheeky tail friskiness" as a legal defense in a sexual harassment case quite yet.
